For a 1-D array, this has no effect. (To change between column and
row vectors, first cast the 1-D array into a matrix object.)
For a 2-D array, this is the usual matrix transpose.
For an n-D array, if axes are given, their order indicates how the
axes are permuted (see Examples). If axes are not provided and
a.shape=(i[0],i[1],...i[n-2],i[n-1]), then
a.transpose().shape=(i[n-1],i[n-2],...i[1],i[0]).

Parameters:

axes : None, tuple of ints, or n ints

None or no argument: reverses the order of the axes.

tuple of ints: i in the j-th place in the tuple means a‘s
i-th axis becomes a.transpose()‘s j-th axis.

n ints: same as an n-tuple of the same ints (this form is
intended simply as a “convenience” alternative to the tuple form)
